Royce Ayr Solid Carbide Up-Cut "O" Flute Router Bit - 3/8" Dia x 1-1/8" Cut
Single-Flute O-Flute Upcut
Hard-Plastic Router Bit
Solid-carbide, right-hand O-flute upcut router bit designed for routing hard plastics. Its 3/8-inch cutting diameter, 1-1/8-inch cutting edge, 3/8-inch shank, and 3-inch overall length provide an extended cutting format for deeper profiles and efficient chip removal in compatible CNC routing applications.
Main Product Description
The Royce Ayr Single-Flute O-Flute Hard-Plastic Upcut Router Bit R63-71608 is engineered for routing hard plastics in compatible CNC systems. Its 0.3750-inch cutting diameter and 1.125-inch cutting edge provide an extended configuration for deeper profiling, slotting, trimming, and controlled material removal in rigid-plastic applications.
The single-flute O-flute geometry provides a large chip space, while the upcut form carries chips away from the cutting zone. This combination supports effective chip evacuation, helps limit chip recutting, and reduces heat accumulation when operated with suitable hard-plastic machining parameters.
The 0.375-inch shank and 3.000-inch overall length require a compatible precision collet or approved toolholder. Before production, verify collet condition, runout, right-hand spindle rotation, tool projection, spindle speed, feed rate, depth per pass, workholding, plastic compatibility, and chip extraction.
Best Fit Applications
Product Highlights
Extended 1-1/8-Inch Cutting Edge
The extended cutting edge supports deeper profiles and slotting operations in compatible hard-plastic materials.
Single-Flute O-Flute Geometry
The large flute space supports chip formation and evacuation while routing rigid plastic substrates.
Rigid 3/8-Inch Tool Format
The matching 3/8-inch cutting diameter and shank support secure precision toolholding for deeper CNC routing operations.
Compatibility & Installation Notes
Confirm that the CNC router spindle or toolholder accepts an exact 3/8-inch (9.525 mm) shank and provides sufficient clearance for the 3-inch (76.2 mm) overall length. Inspect the collet and nut, minimize unsupported tool projection, verify right-hand rotation and runout, and establish spindle speed, feed rate, depth per pass, workholding, hard-plastic compatibility, and chip extraction according to the machine and approved shop procedures.
Improve Deep Hard-Plastic Routing
The Royce Ayr Single-Flute O-Flute Hard-Plastic Upcut Router Bit R63-71608 provides a solid-carbide solution for routing hard plastics. Its 3/8-inch diameter, 1-1/8-inch cutting edge, 3/8-inch shank, single-flute geometry, and 3-inch overall length support deeper profiling, slotting, trimming, and production routing.
Polished O-flute geometry and an upcut form support effective chip removal when the tool is correctly held and operated within suitable hard-plastic machining parameters.
